Description

Cable interface
The present invention relates to a kind of shell wall particularly wall, lid or very useful plate shape cable interface of power distribution cabinet, coupling box or terminal box or meter cabinet etc. of being used for, it has claim 1 feature as described in the preamble.
During with this cable interface, arbitrarily the unit cable of the cross-section of cable all can be introduced in above-mentioned cabinet, case or the box arbitrary position on the cable interface face, even also can make interface enough durable during the inclination lead-in cable, particularly keeps elasticity and sealing.Preparation of cable interface simultaneously and making do not need prerequisite, frock or the special tool(s) of special tectonic.
German patent DE-PS3915007 has proposed the cable interface used on coupling box or power distribution cabinet or the meter cabinet shell wall, and this cable interface is with the soft elastic plate that makes of rubber or thermoplastics for example.On this piece solid elastomeric plate, make many circular holes of the proper alignment successively of three kinds of different sizes according to three kinds of different cable cross-section, make truncated cone shape with the identical soft elastic material of same block of whole plate simultaneously and protrude these holes, and form the membrane structure or the so-called given punch position of projection at the truncated cone top.
This cable interface has important disadvantages: not only will clearly stipulate the locus and the diameter of cable interface circular hole onboard, and the extensibility of truncated cone shape thin flexible film structure is limited, so be subjected to serious restriction when this place's installing cable.In addition, rule of thumb,, consider layout, quantity and the diameter in hole and/or the frustoconical configuration of for this reason arranging needs many different cable interfaces mutually because the border in each hole determines, and with a large amount of instruments and uneconomic storehouse management.
In the known cable interface of another kind, make the plate on plane with porous plastics, as required position and diameter cuts out cable interface with cutter or scissors on the plate.The shortcoming of this cable interface is: interface can not obtain sealing reliably.In addition, need repeatedly cut, thereby blow-by because the extensibility of material is limited, so when actual fabrication, the time-consuming and inaccuracy of home built cable interface.When the inclination lead-in cable, seal unreliable or make and be restricted.Like this, the permanent positiver sealing between cable sheathing and the cable interface is difficult to reach.In addition, also be unreasonable and uneconomic with manually accurately cutting the cable interface that needs.
Task of the present invention is to propose a kind of cable interface above-mentioned shortcoming, the above-mentioned type of having eliminated, and can both make the cable interface of enough durable and positiver sealing in the optional position of flat cable interface simply, to need special tool(s) and economic method with any cable cross-section even under the situation of inclination lead-in cable or installation afterwards.
This task of the present invention solves by the described feature of claim 1 characteristic, and other favourable details is described in every dependent claims.
This tabular, particularly the novel cable interface of planar structure has many advantages: by adopting good-extensibility and the high thermoplastic of fracture strength, especially thermoplastic elastomer (TPE), just cross section size or the sizable cable of external diameter difference can be passed the quite inaccurate hole of simpler production, particularly passing at first in arbitrary position or being preferably in has the so-called via hole that purpose pierces through and cable positive confinement ground is introduced on the position that requires cable to introduce, and used height extends, even the material of high resiliency and high fracture strength also guaranteed reliably when cable tilt passes interface also can be enough hermetically-sealed cable foreskin enduringly.In addition, also having a tangible advantage is to utilize this cable interface face best.In addition, the new-type cable interface made of this simple, reasonable, economic thermoplasticity both can whole be connected with wall, top, the lid of coupling box, power distribution cabinet or terminal box or meter cabinet etc. or in case of necessity with this cable interface as flange shape, particularly whole individual component is installed to above corresponding power distribution cabinet, coupling box or the terminal box etc. with annular reinforcement edge or the frame that material with suitable hardness makes.
Describe embodiments of the invention in detail below in conjunction with accompanying drawing, accompanying drawing is:
Fig. 1 represents to take off the terminal box stereogram of cover plate and cover on each side of terminal box with the cable interface board;
Fig. 2 represents the vertical view of the cable interface of flange shape cable interface, particularly coupling box or power distribution cabinet;
The vertical view of Fig. 3 presentation graphs 2 cable interfaces;
The rearview of Fig. 4 presentation graphs 2 and Fig. 3 cable interface;
The skiagraph of Fig. 5 presentation graphs 2～Fig. 4 cable interface.
Uncovered terminal box 1 usefulness insulating material shown in Figure 1 makes square cross section and is made up of wall 2 and base plate 3.4 expressions install and fix the hole, the tabular cable interface of 5 expressions, and in the scope of wall 2, cable interface injects terminal box 1 is introduced in frame 6,7 expressions by cable interface 5 cable.
But plate-like cable interface 5 forms integral body by macromolecular material, the especially thermoplastic elastomer (TPE) of height extension, high resiliency and high fracture strength, particularly thermoplastic processing and with economic especially manufacture method in the frame 6 of wall 2.
Used elastomeric elongation at break is 400%～700%, and fracture strength can reach 9～14N/mm.So can guarantee that quite thick cable 7 passes the quite simply quite little but via hole 8 that can reliably swell of diameter of making.Simultaneously this elastomeric material clings to sizable elastic pressure on the excircle of cable 7 of any cross section durable and positiver sealing.Also has king-sized advantage simultaneously: the cable interface face 9 permanent quite softnesses that keep.
As shown in Figure 1, the area of cable interface 5 is fully utilized, and promptly the interface of each cable cross-section can be positioned on the optional position of cable interface 5.
Within the scope of the present invention, terminal box 1 shown in Figure 1 is all used with a kind of elastomeric material and is made.
Fig. 2～Fig. 5 represents flange shape cable interface 5, and its periphery is edge or the frame 6 that makes with quite hard material.Tabular or the plane cable interface 5 that makes with elastomeric material connects into integral body with edge or frame 6.As Fig. 3～shown in Figure 5, cable interface 5 is arranged in the frame 6.The so-called given punch position of 11 expressions, particularly mutual coaxial correspondence is arranged on the certain position of flat cable interface 5 in one or both sides for they, particularly distributes as net shape.Given punch position 11 can be a point-like or/and certain diameter is arranged or various different-diameter.
In Fig. 3 and Fig. 4,7 expressions have the cable that passes cable interface 5 of different cross section.Clearly from figure find out, in the scope of each interface surface 9, formed the material of more or less piling up 13, the cross section size of television cable and deciding.These materials of piling up flexiblely are pressed onto on the cable excircle and form reliable and durable sealing.
Particularly edge or available when needed proper metal of frame 6 or the non-metallic fillers reinforcing that makes with thermoplasticity or thermoset plastics.As shown in Figure 4 and Figure 5,14 expression projectioies around sealing, it makes with cable interface 5 identical elastomeric materials.As shown in Figure 5, sealing 14 and cable interface 5 one are reinstated one procedure and are made.Cable interface 5 and sealing 14 22 connect into single piece in flakes by interrupted.For this reason, in frame 6, considered suitable groove 23 by certain distance.
It is synthetic whole to make this flange 10 the most handy two-part thermoplastic injections and/or extrusion or vulcanizate.Particularly, the manufacturing of this flange 10 is carried out with so-called multi-player injection method.
15 expressions have the flange locking device of latch 16 and corresponding fastening bolt 17.As shown in Figures 2 and 3, Zheng Mian fastening screw ailhead 18 has a molded part of immersing oneself in 19 respectively and is used for the engaging screw cutter.Molded part 19 is equipped with a direction locking mechanism 24, with the certain direction rotation in 17 edges of screwdriver operation fastening bolt, particularly only is rotated in a clockwise direction, thus the latch 16 of locking locking device 15.Fastening bolt 17 can not be by molded part 19 along counter rotation.
So for safety and/or prevent the reason destroyed, 15 of locking devices may be by direct actuating latch 16 particularly by the suitable molded part 20 on the latch 16, that is can only operate from the inside of for example power distribution cabinet.
Latch 16 rotatable about 90 ° and the fastening bolt 17 by screw thread and rotatable support mesh.Like this, latch 16 just can axially enough be locked on the distribution box later securely swinging in the distribution box edge edge back of not drawing among the figure inwards.As shown in Figure 4 and Figure 5,21 be illustrated in the O RunddichtringO that effectively seals between frame 6 and the fastening bolt 17.
But this flange 10 advantages of simple and afterwards being contained in economically on branch electronic box or the power distribution cabinet are particularly because only need have a suitable rectangular flange hole just much of that cashier's office in a shop.In addition, not only can but also can be used for coupling box or the power distribution cabinet that thickness of slab is 1.5～5mm by adjustable for height latch 16 from the inside from the above-mentioned flange locking device of outside actuating.This new-type cable interface also can replace so-called standard cable interface.
Within the scope of the present invention, be not used in cable interface and also can be used for pipe or hose connection.Simultaneously, the present invention is not limited to and is used for electric installation, and this flexible cross-linked material also can be used as health, heating, air-conditioning and surge, interface, particularly coupling box or the power distribution cabinet of pneumatic fitting limit, refer to the interface of concealed installation heater chain terminal box especially.
